AS1664

AS1664 is an ASN in IANA’s 1–1876 block, which IANA identifies as assigned by ARIN. Its operator, registered organization, country, and network role are Unknown from the supplied evidence. In the combined Route Views observation at 2026-11-06 20:00 UTC, no IPv4 or IPv6 prefixes and no AS_PATH neighbours were observed across route-views2 and route-views6. This is a snapshot result, not evidence that the ASN is dormant or inactive.

The observation records zero IPv4 address estimate and zero peers, with an empty neighbour sample. These are combined counts across the named collectors; they are not separate measurements for each collector. AS_PATH adjacency, when present, would not by itself establish a commercial peer, upstream, or customer relationship. Here, no neighbours were observed in this snapshot.

For identification, treat the ARIN reference only as the allocating RIR for the IANA block, not as an individual assignment record. To investigate a specific address or route, compare its origin ASN and timestamp with current routing data and consult authoritative registration records. This snapshot alone cannot identify an operator, deployment, traffic prevalence, or security status.

Triage

The zero counts describe this combined observation only; they do not establish inactivity or security status.

Identification

Confirm a suspected route using timestamped routing data and authoritative registration records; no operator or organization is identified by the supplied evidence.
